What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: aircraft landed without contacting the tower. An ATC employee approached the pilot after parking. It was determined that the pilot transmitted on the wrong frequency and got no response. The pilot thought the tower was closed and reported the downwind base and final legs and landed. The ATC employee gave the pilot the correct frequencies and he later departed without further incident. I counseled the pilot in the areas of pre-flight planning, ATC procedures and night operations specifically for lck airport. He demonstrated an excellent attitude and said he'd learned from this incident so as not to repeat it. Airman competency is applicable simply because he tuned the wrong frequency. A violation of FAR 91.103 exists because the pilot did not know for certain the hours of operation of lck tower. There are several publications available containing this info.
